Philadelphia Science Fiction Society

The Philadelphia Science Fiction Society (PSFS) is a science fiction club in Philadelphia, Pennsylvania. PSFS is the second oldest group in science fiction fandom and hosted what is considered by some to be the first science fiction convention.[1] Anyone living in the greater Philadelphia area and interested in science fiction, fantasy, horror, whether written or on TV or in the movies; SF, fantasy, and horror art; gaming, board games or video games; comic books/graphic novels; and related arts is welcome.

The PSFS Constitution requires that a person must have attended three meetings before being voted into membership. The traditional club greeting for a person voted in is, "Pay your dues!" shouted in unison.


PSFS was formed in October 1935 as a merger of the 11th chapter of the Science Fiction League (chartered the previous January by Milton A. Rothman), and the Boy's Science Fiction Club, founded at about the same time.[2] It adopted its present name in early 1936. According to John Baltadonis (one of its founders), the new name was inspired by an illuminated sign saying "PSFS" on the Philadelphia Savings Fund Society's building. The idea was that the science fiction group could then claim that the building was its clubhouse. In 1944, it merged with another Philadelphia SF club, the Philadelphia Futurians, and retained the PSFS name.[3]

PSFS meets monthly, usually on the second Friday of the month. Meeting usually have a guest speaker. The Annual meeting is held in January and sees the seven members of the PSFS Board (President, Vice President, Secretary, Treasurer, and three at-large members) report on their activities for the past year, and elections for new officers are held.
